摘要
目的:对比分析Embase.com和PubMed的检索结果,为科研人员推荐最适合的检索工具和提高检索效率。方法:选取8个不同学科的检索词,在PubMed和Embase.com中分别采用主题词检索和带有自动转换功能的基本检索两种途径检索。结果:8个检索词在检索中出现6种不同情况。结论:通过主题词检索,总体来说Embase.com检全率要高于PubMed;带有自动转换功能的基本检索,两个数据库都会出现错误转换,但从转换的原理上看,PubMed的查准率更高。
Objective To recommend the appropriate retrieval tools for scientific researchers and trieval efficiency by comparatively analyzing the retrieval results from PubMed and Embase. com. improve their re- retrieval terms from different subjects were used to retrieve PubMed and Embase. com by subject headings and basic retrieval methods than can automatically transfer their function. Results Six different results were retrieved from PubMed and Embase. com with 8 retrieval terms. Conclusion The recall ratio is higher in Embase. com than in PubMed when they are retrieved by subject headings while the accuracy ratio is higher in PubMed than in Embase. com when they are retrieved by basic retrieval methods than can automatically transfer their function although error transformation occurs in both PubMed and Embase. com.
